Transcanalicular Diode Laser Assisted Dacryocystorhinostomy

蔡悅如 Yueh-Ju TsaiTaiwan Speaker Transcanalicular Diode Laser Assisted DacryocystorhinostomyTranscanalicular laser dacryocystorhinostomy is a minimally invasive surgical intervention for nasolacrimal duct obstruction. The procedure involves creating a direct osteotomy by advancing a laser fiber through the canaliculus to ablate the bone and soft tissue separating the lacrimal sac from the nasal cavity. This approach offers distinct advantages, including the absence of cutaneous scarring, superior hemostasis, and preservation of the physiological lacrimal pump mechanism; it also serves as an effective salvage technique for failed DCRs. We utilized an 810-nm diode laser, and a video demonstration of the intraoperative technique will be presented. Due to the reduced operative time and minimal bleeding, this procedure is well-suited for local anesthesia, making it particularly advantageous for elderly patients.
